Description Felix Möller 2009-09-09 07:29:38 UTC 
Description of problem:
I am using the update-testing repo. Which contains the 2.6.30 kernel series.

Updating to a 2.6.30 kernel prevents me to start Xorg. 

Booting in to init 3 and then entering startx manually gives me a blinking Caps Lock.

This is about a Thinkpad T400 running 32bit userland with 4GB RAM.

I just experienced this as well on a Lenovo x61. It appears to be related to the new PAE kernel.

kernel-PAE-2.6.29.6-217.2.16.fc11.i686 works. 
kernel-2.6.30.5-43.fc11.i686 works.
kernel-PAE-2.6.30.5-43.fc11.i686 does not work. 

# rpm -q kernel && rpm -q kernel-PAE && rpm -q xorg-x11-drv-intel
kernel-2.6.30.5-43.fc11.i586
kernel-PAE-2.6.29.6-217.2.16.fc11.i686
kernel-PAE-2.6.30.5-43.fc11.i686
kernel-PAE-2.6.29.6-217.2.8.fc11.i686
xorg-x11-drv-intel-2.7.0-7.fc11.i586

As the original comment states, either booting into run level 5 or running startx causes a kernel panic when the x server starts.
